Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33587778, here are decompositions:

17 + 33587761 = 33587778
41 + 33587737 = 33587778
47 + 33587731 = 33587778
71 + 33587707 = 33587778
101 + 33587677 = 33587778
109 + 33587669 = 33587778
131 + 33587647 = 33587778
197 + 33587581 = 33587778

Showing the first eight; more decompositions exist.

IPv4 address

As an unsigned 32-bit integer, this is the IPv4 address 2.0.130.66.

Address: 2.0.130.66
Class: public
IPv4-mapped IPv6: ::ffff:2.0.130.66

Public, routable address (assignable to a host on the internet).

Possible US bank routing number

This passes the ABA routing number checksum and matches the Federal Reserve numbering scheme.
